    Neuromuscular Physiology

Research Interests

The aim of my research program is to understand the underlying mechanisms of fatigue. Specifically, my work examines the link changes in cerebral blood flow and indices of neuromuscular fatigue during environmental stress (such as hyperthermia and hypoxia).
